Kotlin Hello World

Kotlin is a modern, powerful, statically-typed programming language that was developed by JetBrains, the same company that created the IntelliJ IDEA IDE. Kotlin is designed to be interoperable with Java and other programming languages, making it a great choice for developing Android apps, backend services, and web applications.

Getting Started

To get started with Kotlin, you'll need to download and install the Kotlin compiler, which you can do from the official Kotlin website (https://kotlinlang.org/). Once you have the Kotlin compiler installed, you can start writing Kotlin code right away.

Hello World Example

Here is a simple "Hello World" program in Kotlin:

fun main() {
    println("Hello, World!")
}

This program defines a function called main that takes no arguments and returns no value. The body of the function contains a single statement that uses the println function to print the message "Hello, World!" to the console.

Running the Program

To run this program, you'll need to save the code in a file with a .kt extension, such as hello.kt. Then, you can use the command-line compiler to compile and run the program:

$ kotlinc hello.kt -include-runtime -d hello.jar 
$ java -jar hello.jar
Hello, World!

Alternatively, you can use an IDE such as IntelliJ IDEA, which has built-in support for Kotlin. Just create a new Kotlin project, create a new file, and copy the code into the file. Then, you can run the program from within the IDE by clicking the "run" button.

Conclusion

Kotlin is a powerful and modern programming language that is gaining in popularity. With its interoperability with Java and other programming languages, it is a great choice for building a wide range of applications. We hope this "Hello World" program has helped you get started with Kotlin, and we encourage you to explore more of what this language has to offer.
